The Symbolism of Water Many works of literature use symbols to represent abstract ideas. One symbol that is commonly used is water. Water is a viable symbol because it is versatile. It can be used to represent many different ideals because water in itself is ever changing.
any milk or milk by-products, such as cheeses, ice cream, butter, etc is considered dairy. Soy milk is okay, as is rice milk. Eggs are considered dairy, but as they don't come from a cow, I am not sure that would be included in your excluding dairy--same goes for goat's milk and it's by-products.
I don't know anyone who considers eggs to be classed as dairy. But I do know that dairy, by definition, relates to milk production or milk products. If you look into the etymology of dairy, it once used to refer to the place where milk or milk products were sourced/produced. the definition of dairy.
